You mean cracking sprites ?What damage is appearing in esf of only cracking?.
No, limit is 32 players. I doubt if ESF Final can handle 32 players without lag.You can set the maximum when making servers, or you can just join a server with fewer people. But I think the limit for Half-Life is 16, but for playability most servers will be a lot less?
I don't remember as it's been a long time since I played 1.2.3
